Houston to Hattiesburg/Laurel

What the Data Says About IAH to PIB

The Houston to Hattiesburg/Laurel corridor (IAH → PIB) covers roughly 372 miles and is served by 1 carrier, based on Bureau of Transportation Statistics reporting. Across 2,926 flights in the dataset, this route posts a 83.2% on-time rate with an average delay of 100.8 minutes when flights run late. Over the most recent 24 months of BTS data, 1,254 flights were recorded on this pairing — 24 cancelled (1.9%) and 6 diverted (0.5%). Those baseline metrics tell you what to expect before you book.

Having 1 carrier on the route matters: more carriers generally means more daily schedule options, competitive pricing, and redundancy when flights are cancelled. With 2,926 total flights analyzed, the 83.2% on-time figure is statistically meaningful rather than a small-sample fluke. The 100.8-minute average delay applies only to flights that actually ran late, so it is not the average wait across all departures — the majority of flights on this route depart on time under the BTS definition of a delay (15+ minutes past schedule).

Looking at recent months, Dec 2024 posted the best performance on this corridor at 91% on-time, while Apr 2025 came in at 61% on-time — a 30-point gap between best and worst recent month. For travelers evaluating the IAH to PIB route, the combination of a 83.2% on-time rate, 100.8-minute average delay, 1.9% recent cancellation rate, and 1 available carrier is the concrete summary of what BTS data shows about reliability on this pairing.
